Abstract
Mutation breeding using radiation has been shown to be an effective and important tool in incorporating specific desirable agronomic values characteristics in vegetable crops including pea (Pisum sativum L.). In the present study, dry seeds of ‟Master - B” Pea cultivar were exposed to 0, 10, 20 and 30 Krad doses of gamma rays, and variability in growth characteristics, earliness, and seed yield were investigated in M1, M2 and M3 generations. Analysis of variance showed significant difference among M1-plants as well as M2 and M3-families for the studied traits with higher variability in high doses of gamma ray treatments. In M3–generation, lines with significant increases in yield parameters such as number of pods per plant and number of seeds per plant were obtained. Mutant line number 8 was out yielded in terms of number of pods and seeds per plant. These results indicate that induced mutation breeding by gamma ray is a valid and effective crop breeding method in pea.
